I'm working at a research lab where we are designing assistive musical instruments for disabled musicians. A couple projects involve building guitars that can be played one handed, and have all the chord changes handled by transposing/muting the 6 open notes played on the strings according to guitar tabs which encode finger positions on the fret board.

I don't play guitar, and all my background music theory is primarily keyboard based. Learning about guitar tabs, and finger positions and techniques, a lot about guitar based music makes much more sense, and if you even just look at the data behind guitar tabs is smells like it's own dialect of music.

Take a look at this chords database. https://tombatossals.github.io/react-chords/

That's just chords, the dynamics are a whole other dimension of expression and communication. A single note with expressive control can communicate a lot.

And then rhythm! A game my daughter and I play is to name that song just by clapping it.

The bandwidth of communication in music is really quite astounding.

It is the original virtual reality.
